Plykit for Amazon KDP
Build a draft one page at a time, review every page, then run your own KDP preflight for trim, bleed, margins, page count and cover fit before you publish.
Start a coloring book draftTools
Draft one page at a time around a chosen character reference, review every result, then export a 300 DPI interior draft for your own KDP preflight.
Upload the cover template Amazon generated for your book and the real trim, spine and bleed are read off the file — including its actual 600 DPI.
Work out full-wrap dimensions and spine width from page count and paper type. Free, no account needed.
Sample books

Seasonal niches spike hard on KDP — Halloween searches start climbing in August. A consistent mascot character across seasonal scenes is exactly what used to require an illustrator.
Guides

The same ten prompts across three models, with original files, credits and line-art defects.
Why re-prompting cannot hold a character, what does, and the five line-art defects to check before you upload an interior.
